    • Evidence of a Liquid-Liquid Phase Transition in Hot Dense Hydrogen 

      Dzyabura, Vasily; Zaghoo, Mohamed; Silvera, Isaac F. (Proceedings of the National Academy of Sciences, 2013)
      We use pulsed-laser heating of hydrogen at static pressures in the megabar pressure region to search for the plasma phase transition to liquid atomic metallic hydrogen. We heat our samples substantially above the melting ...

    • Evidence of Adaptation from Ancestral Variation in Young Populations of Beach Mice 

      Domingues, Vera S.; Poh, Yu-Ping; Peterson, Brant K.; Pennings, Pleuni; Jensen, Jeffrey D.; Hoekstra, Hopi E. (Wiley-Blackwell, 2012)
      To understand how organisms adapt to novel habitats, which involves both demographic and selective events, we require knowledge of the evolutionary history of populations and also selected alleles. There are still few cases ...

    • Evidence of Annealing Effects on a High-Density Si/SiO2 Interfacial Layer 

      Kosowsky, S. D.; Pershan, Peter S.; Krisch, K. S.; Bevk, J.; Green, M. L.; Brasen, D.; Feldman, L. C.; Roy, P. K. (American Institute of Physics, 1997)
      Thermally grown Si(001)/SiO\(_2\) samples were studied by x-ray reflectivity. Fits of model electron density profiles to the data reveal the existence of an interfacial layer at the Si/SiO\(_2\) interface up to 15-Å-thick, ...

    • Evidence of protein-free homology recognition in magnetic bead force–extension experiments 

      (O’) Lee, D. J.; Danilowicz, C.; Rochester, C.; Kornyshev, A. A.; Prentiss, M. (The Royal Society Publishing, 2016)
      Earlier theoretical studies have proposed that the homology-dependent pairing of large tracts of dsDNA may be due to physical interactions between homologous regions. Such interactions could contribute to the sequence-dependent ...

    • Evidence of System Justification in Young Children 

      Baron, Andrew; Banaji, Mahzarin R. (Wiley-Blackwell, 2009)
      The near ubiquity of ingroup preference is consistent with the view that it is an automatic consequence of social categorization, possibly a basic foundation of intergroup relations. However, research with adults has ...

    • Evidence revisited: literature on smart specialisation calls for more mixed research designs 

      Fellnhofer, Katharina (Inderscience Publishers, 2017)
      The aim of this paper is to present an overview of the applied research methods that have been used to examine smart specialisation. For this review, papers from various sources were collected and reviewed multiple times. ...

    • Evidence: What the U.S. Research Shows about Worker Ownership 

      Blasi, Joseph; Freeman, Richard Barry; Kruse, Douglas (Oxford University Press, 2017)
      The Oxford Handbook of Mutual, Co-operative, and Co-Owned Business investigates all types of 'member owned' organizations, whether consumer co-operatives, agricultural and producer co-operatives, worker co-operatives, ...

    • Evoked itch perception is associated with changes in functional brain connectivity 

      Desbordes, Gaëlle; Li, Ang; Loggia, Marco L.; Kim, Jieun; Schalock, Peter C.; Lerner, Ethan; Tran, Thanh N.; Ring, Johannes; Rosen, Bruce R.; Kaptchuk, Ted J.; Pfab, Florian; Napadow, Vitaly (Elsevier, 2014)
      Chronic itch, a highly debilitating condition, has received relatively little attention in the neuroimaging literature. Recent studies suggest that brain regions supporting itch in chronic itch patients encompass sensorimotor ...

    • Evolution after Introduction of a Novel Metabolic Pathway Consistently Leads to Restoration of Wild-Type Physiology 

      Carroll, Sean; Marx, Christopher J (Public Library of Science, 2013)
      Organisms cope with physiological stressors through acclimatizing mechanisms in the short-term and adaptive mechanisms over evolutionary timescales. During adaptation to an environmental or genetic perturbation, beneficial ...

    • Evolution and emergence of infectious diseases in theoretical and real-world networks 

      Leventhal, Gabriel E.; Hill, Alison L.; Nowak, Martin A.; Bonhoeffer, Sebastian (Nature Pub. Group, 2015)
      One of the most important advancements in theoretical epidemiology has been the development of methods that account for realistic host population structure. The central finding is that heterogeneity in contact networks, ...

    • Evolution and Loss of Long-Fringed Petals: A Case Study Using a Dated Phylogeny of the Snake Gourds, Trichosanthes (Cucurbitaceae) 

      de Boer, Hugo J; Schaefer, Hanno; Thulin, Mats; Renner, Susanne S (BioMed Central, 2012)
      Background: The Cucurbitaceae genus Trichosanthes comprises 90–100 species that occur from India to Japan and southeast to Australia and Fiji. Most species have large white or pale yellow petals with conspicuously fringed ...

      Niblett, Anthony; Posner, Richard A.; Shleifer, Andrei (University of Chicago Press, 2010)
      Efficient legal rules are central to efficient resource allocation in a market economy. But the question whether the common law actually converges to efficiency in commercial areas has remained empirically untested. We ...

      McHorse, Brianna K; Biewener, Andrew; Pierce, Stephanie (Oxford University Press (OUP), 2019-05-24)
      Horses are a classic example of macroevolution in three major traits—large body size, tall-crowned teeth (hypsodonty), and a single toe (monodactyly)—but how and why monodactyly evolved is still poorly understood. Existing ...
